Week 6

(Module 1 Topic 2 Lesson 1: Area)

Learning objective = Students progressively derive the formulas for the area of a parallelogram, triangle, and trapezoid by using composition and decomposition of polygons with known area formulas. They use their formulas to calculate the area of parallelograms, triangles, and trapezoids. They also generalize that triangles with congruent bases and congruent heights have the same area.

Parents can support learning at home by helping students connect this week’s lesson to real-life examples and practice explaining their thinking. Encourage your child to explain each step aloud rather than simply memorize a rule = SAMPLE TEST QUESTIONS + MORE QUESTIONS

***If your child needs more challenge, they can move at a faster pace by using this site to study the concepts of future lessons. Mr. Pierre will strive to prepare lessons two weeks ahead of the current week. Also, Khan Academy is a great enrichment resource***

Area of a Triangle | Grades 3-5, 6-8 Figure Attributes of One Category Apply to Subcategories (Grade 5) Teaching and Lesson ResourcesWatch Geometry Gal explain how to find the area of a triangle, comparing the formula for the area of this two-dimensional shape to that of a quadrilateral, in this video from KCPT.

Measurement: Area | Grades 9-12, 13+ Area, Surface Area, and Volume Teaching and Lesson ResourcesIn this video, viewers learn how to calculate area. Area is the measure of the surface inside a flat figure. Area is measured in square units. Multiply the length times the width to get the square units. This video segment is from the GED Connection "Measurement" video.

Surface Area , Area and Volume: The Big Sleep | Cyberchase | Grades 3-5, 6-8 Composing and Decomposing to Find Area of Triangles, Quadrilaterals, and Polygons (Grade 6) Teaching and Lesson ResourcesIn this video from Cyberchase, Bianca is planning a sleepover birthday party. To figure out the maximum number of friends she can invite, she decides to count how many sleeping bags she can fit over the area of her living room floor. In the accompanying classroom activity, students use the concepts presented in the video to determine the area of multiple shapes. This resource is part of the Math at the Core: Middle School Collection.

Area Model | Grades 3-5 Multi-Digit Arithmetic Teaching and Lesson ResourcesWhen first learning to multiply two two-digit numbers your child will use the area model.To start, your child will use her knowledge of place value to decompose into tens and ones. To decompose means to break apart. Let’s decompose these numbers by the value of each digit.The value of two tens is twenty. The value of three ones is three. Three tens is thirty. And five ones is five. Decomposing numbers allows your child to use the multiplication fluency she developed in third grade to multiply large numbers with mental math.So, what is twenty-three times thirty-five?Three tens times two tens equals sixty tens or six-hundred. Thirty tens times three equals nine tens or ninty. Twenty tens times five equals ten tens or one-hundred. And three times five equals fifteen. Your child will then add these products together. Six-hundred plus ninety equals six-hundred ninety. One-hundred plus fifteen equal one-hundred fifteen. By fourth grade, your child will fluently add three-digit numbers, like this, using the standard algorithm.Your child can clearly see why twenty-three times thirty-five equals eight-hundred-five. The area model gives your child a visual representation that decomposes the numbers she is multiplying. At this point in fourth grade, your child is developing a pictorial level of understanding, which will give her a strong foundation for using partial products and, later, using the standard algorithm to multiply.
